Your Neighbor in Home Comfort Since 1987

Since 1987, Groff's Heating & Plumbing has been helping families in Lancaster, Chester and York counties live better with high-efficiency heating and cooling, plumbing, electrical service and repair and bathroom remodeling.

Family owned and operated, Groff's Heating & Plumbing began as an HVAC company in the garage of DeVon Groff in Mountville, PA. In 1991, master plumber Dennis Dagen joined the company and developed the plumbing division. In 1993, Denny and DeVon formed a partnership and incorporated the business to create Groff's Heating & Plumbing.

In 2000, Denny and DeVon officially launched the electrical division and relocated the business to its present location in Willow Street, PA. After graduating from college, DeVon's son Adrian joined the company and now serves as Vice President, managing all aspects of Human Resources.
